Abstract
The utility model relates to a heat exchanger heat exchanging plate, in particular to a wide flow passage plate type heat exchanger heat exchanging plate, and belongs to the technical field of metal anti-corrosion and anti-abrasion. The wide flow passage plate type heat exchanger heat exchanging plate comprises a heat exchange plate, wherein the heat exchange plate is an interlayer structure and is composed of two heat exchange plates whose single sheet two ends are flatly butted, a layer of finished product nickel-chromium chromium carbide powder coating with the granularity of 300 to 500 meshes is arranged on the flat butt positions of two ends of the heat exchange plates and an oblique surface transition position, and the thickness of the coating is 0.3 to 0.5mm. The utility model aims at providing people with a wide flow passage plate type heat exchanger heat exchanging plate with simple working procedures and low production cost, simultaneously, the set coating factor of porosity is low, the structure intensity and the surface hardness are high, and the heat exchanging plate can prevent corrosion and abrasion.
Description
Technical field
The utility model relates to a kind of heat exchanging plate of heat exchanger, specially refers to a kind of wide-runner plate heat exchanger heat exchanger plates, belongs to anti-corrosion of metal wear-proof technique field.
Background technology
At present, in traditional alumina producer seed decomposition process, the cooling seed solution is to adopt wide-runner plate heat exchanger, seed solution flows into from an end in stacked heat exchange plate gap, taken away heat by the cooling water that rightabout in the plate flows into, with seed solution cooling, so heat exchanger heat exchange plate when operation is in high temperature for a long time and has in the alkaline seed solution, and especially two ends can be subjected to the strong corrosion and the high speed impact of seed solution.Use Heat exchanger sheet heavy corrosion after a period of time, the infiltration phenomenon appears in the position that has even be worn through, and has had a strong impact on the normal use of heat exchanger.Just need overhaul in general 2～3 months, and can influence production, reduce output, reduce economic benefit.
A kind of heat sink that adds the broad passage plate heat exchanger that is provided with the erosion resistance strengthening layer that is made of stratification formula high hardness alloy powder sprayed coating and high-intensity resin sealing of hole layer on the outer surface of heat exchanger plates two ends flat part and inclination divergent section is disclosed in CN101261098A application for a patent for invention Publication Specification, and a kind of high hardness alloy powder superhard coating that is made of nickel and tungsten carbide disclosed, though can solve the problem of heat exchanger plates anticorrosion antiwear, but its operation more complicated, must carry out sealing of hole, therefore production cost is higher, the coating porosity that adopts nickel and tungsten carbide to spray simultaneously is higher, and is also lower aspect bond strength and case hardness.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides to people that a kind of operation is simple, production cost is low, simultaneously the wide-runner plate heat exchanger heat exchanger plates of low, the bond strength of the coating porosity of She Zhiing and case hardness height and anticorrosion antiwear.
For achieving the above object, the utility model adopts following technical proposals: a kind of wide-runner plate heat exchanger heat exchanger plates, comprise heat exchange plate, this heat exchange plate is a sandwich, constitute by two flat butt joints in heat exchanger plates monolithic two ends, at the flat joint in heat exchange plate two ends and chamfered transition position one deck granularity being set is 300～500 purpose finished product nickel chromium triangle chromium carbide powder coatings, and the thickness of coating is 0.3～0.5mm; One deck nickel chromium triangle chromium carbide coating is set on heat exchange plate.
Because the utility model is provided with one deck nickel chromium triangle chromium carbide coating at flat joint in heat exchange plate two ends and chamfered transition position, and the nickel chromium triangle chromium carbide has hardness height, anti abrasive performance, therefore can make Heat exchanger sheet reach anticorrosive, wear-resisting effect.
Contrast CN101261098A patent of invention open source literature, the utility model is provided with one deck nickel chromium triangle chromium carbide coating, the porosity of nickel chromium triangle chromium carbide coating is less than 1%, and the porosity that nickel and tungsten carbide coating be set is 10～15%, because the porosity of nickel chromium triangle chromium carbide coating is set, and itself is just very low, therefore do not need to carry out sealing of hole, just can meet and exceed the same effect of disclosed invention in the contrast invention document, make that production process of the present utility model is simple and production cost is also lower.
Contrast CN101261098A patent of invention open source literature, the utility model is provided with one deck nickel chromium triangle chromium carbide coating, the bond strength of nickel chromium triangle chromium carbide coating is at 70～100Mpa, case hardness is at 50～58HRC, and the bond strength that nickel and tungsten carbide coating be set is at 30～50Mpa, case hardness is at 20～30HRC, and therefore anticorrosion antiwear performance of the present utility model all will be compared better than the heat sink performance of the disclosed broad passage plate heat exchanger of invention document.
